Printing issues from photoshop to epson 7900

when printing from photoshop CC to an epson 7900 printer there are issues that occur. I work for a photography dept for a university and am well versed with these processes. However, starting yesterday when an image is sent to print the printer will push out 10 inch of paper, followed by printing a truncated 8x2 version of the image. this is roll paper and i am using custom paper sizes. i don't know what the problem is but any help that some on can give would be great
